WHEELED PLOW.

- Specification of Letters Patent.

Patented Aug. 9, 1910.

Application fled August 17, 1908. Serial No. 448,871.

To all whom it may concern:

Be it known that I, LEWIS E. WATERMAN, a. citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Wheeled Plows, ofwhich the following is a specification.

The object of this invention is to support a plowing disk in a manner topermit it to raise when it strikes an obstruction, and applied springforce to return it and hold it in its working position.

The further object of this invention is to construct a plowing disk witha depressed center, and to the rear face of the disk is connected thebearing for the disk, thereby utilizing the proper length of bearingwithout it projecting beyond the cutting edge of the disk.

In the accompanying drawings, Figure 1 is a plan view of a wheeled plowcontaining my improvements. Fig. 2 is a cross section of the main frameshowing one of the plowing disks and its connections therewith ulldotted lines 0 b Fig. 1. Fig. 3 is a cross section of the main frame,and through the support for a plowing disk on dotted line Fig. 1. Fig. 4is a. plan view of the bracket support for a plowing disk, in which aportion of one bearin is in section.

The main frame 1 1s supported by the front furrow wheel 2, rear furrowwheel 3 and land wheels 4. Each of the wheels is provided with a lever5, and a toothed segment 6 for regulating the height of the frame. Adraft bar 7 has connections 8 with the main frame.

The main frame 1 supports a plurality of plowing disks, and adescription of one will answer. A bracket 9 is connected to the mainframe by the U bolts 10, and is provided with an uprising projection 11and two rearwardly extending branches 12. The support for the plowingdisk 13 is composed of the arms 14 and 15 in bell-crank form, and thecross bar 16 supported by the bearings 17 formed in the branches 12. Tothe free end of the arm 15 are pivoted two links 25, and to the freeends of these links are pivotally connected two links 26 which havetheir free ends pivotally connected to the uprising projection 11. Across-bar 27 connects the two links 26, and through it passes a rod 28having its lower end connected to the bracket 9 by the pin 29. The upperportion of this rod is screw-threaded and receives a nut 30 on itsscrew-threaded portion. A coiled spring 31 surrounds the rod 28 betweenthe nut 30 and the cross-bar 27. To the bracket 29 is connected a stop32 against which the links 25 will strike when the plowing disk israised, and prevent too great a lock of the links.

-In use should the plowing disk 13 strike an obstruction, it will yieldupwardly into the position shown in dotted lines Fig. 3, and this upwardaction will be against the action of the spring 31. The weight of theplowing disk will cause the disk to drop into working position, and thedownward force exerted by the spring 31 Will hold the plowing diskyieldingly to its work.

I claim as my invention.

In a plow, the combination with a beam, of a bracket resting on thebeam, U shaped clips connecting the bracket to the beam, a plowingmember pivoted to the beam and having an upstanding arm, an uprisingprojection on the bracket between the clips, toggle links pivoted to theupstanding projection and to the arm of the plowing memher, a rodpivoted to the bracket adjacent to the uprising projection and extendingtransversely of one of the links, a cross bar pivoted to said link andsliding on the rod, and a spring mounted on the rod above the cross barand bearing downwardly against said cross bar.

2. In a plow, the combination with a support, of an upwardly swinginplowing device pivoted thereto, means or yieldingly resisting" theupward movement of the device, a mounting for the yielding means, a stopfor limiting the swinging movement of the plowing device, and commonmeans for securing the stop and mounting to the suport. p 3.
